Answer:
52 m²
Step-by-step explanation:
12x3 = 36
2 x (11-3) = 2x8 = 16
36+16 = 52
Times the 4 and the 3 and then add 5. PEMDAS- Parenthesis, exponents, multiplication, division, addition, subtraction.
Answer:
Lateral surface area of cone = π(3)(5)
Lateral surface area of cone = 47.1 unit² (Approx.)
Step-by-step explanation:
Given:
Radius of cone = 3 unit
Height of cone = 4 unit
Find:
Lateral surface area of cone
Computation:
Slant height of cone = √Radius² + Height²
Slant height of cone = √3² + 4²
Slant height of cone = √9 + 16
Slant height of cone = √25
Slant height of cone = 5 unit
Lateral surface area of cone = πrl
Lateral surface area of cone = π(3)(5)
Lateral surface area of cone = (3.14)(15)
Lateral surface area of cone = 47.1 unit² (Approx.)
